Markdown Formatter – Clean Markdown Spacing | MZ Smart Tools House

Normalize common Markdown whitespace, heading spacing and list markers while preserving fenced code blocks and document content.

Clean Markdown formatting without executing or inventing content.

How it works

Trailing whitespace and excessive blank lines are normalized outside fenced code blocks; content inside code fences is preserved.

Normalize '#Heading' to '# Heading' and repeated blank lines to consistent spacing.

Fenced code-block contents are preserved.

The formatter is conservative and focuses on whitespace and basic structural cleanup.
